## Official release
|
|
|
|
To install LangChain run:
|
|
|
|
import Tabs from '@theme/Tabs';
|
|
import TabItem from '@theme/TabItem';
|
|
import CodeBlock from "@theme/CodeBlock";
|
|
|
|
<Tabs>
|
|
<TabItem value="pip" label="Pip" default>
|
|
<CodeBlock language="bash">pip install langchain</CodeBlock>
|
|
</TabItem>
|
|
<TabItem value="conda" label="Conda">
|
|
<CodeBlock language="bash">conda install langchain -c conda-forge</CodeBlock>
|
|
</TabItem>
|
|
</Tabs>
|
|
|
|
This will install the bare minimum requirements of LangChain.
|
|
A lot of the value of LangChain comes when integrating it with various model providers, datastores, etc.
|
|
By default, the dependencies needed to do that are NOT installed.
|
|
However, there are two other ways to install LangChain that do bring in those dependencies.
|
|
|
|
To install modules needed for the common LLM providers, run:
|
|
|
|
```bash
|
|
pip install langchain[llms]
|
|
```
|
|
|
|
To install all modules needed for all integrations, run:
|
|
|
|
```bash
|
|
pip install langchain[all]
|
|
```
|
|
|
|
Note that if you are using `zsh`, you'll need to quote square brackets when passing them as an argument to a command, for example:
|
|
|
|
```bash
|
|
pip install 'langchain[all]'
|
|
```
|
|
|
|
## From source
|
|
|
|
If you want to install from source, you can do so by cloning the repo and be sure that the directory is `PATH/TO/REPO/langchain/libs/langchain` running:
|
|
|
|
```bash
|
|
pip install -e .
|
|
```
